The Nautamouse product concept is a computer input device for navigation and manipulation in 3D for CAD, games and GIS applications.
It uses three standard optical or laser mice sensors to measure translation and rotation in each dimension, which are combined with a USB hub.
The device contains a new six degree of freedom parallel mechanism to isolate and measure each component of movement, and appears to the user as a tennis ball size sphere on a mounting assembly.
Here are some examples of the prototype in use.
The device is the subject of Australian Patent Application No. 2012202737.
I am interested in expressions of interest to sell this concept.
